Lenovo desktop PCs are widely used in homes and businesses for work, entertainment, and data storage. However, when a hard drive begins to fail, it can cause system instability, frequent freezing, and eventual data inaccessibility, putting important files at risk.
This case study details how we successfully recovered critical files for a client in Guildford from a Lenovo desktop PC hard drive, after system crashes and file inaccessibility were caused by a failing HDD.
As Guildford Data Recovery, Surrey’s oldest and best data recovery company, we have 25 years of experience using hardware diagnostics, deep sector scanning, and forensic data extraction techniques to restore lost files securely.
Lenovo Desktop PC Crashing & Files Not Accessible
A Guildford-based client contacted us after their Lenovo desktop PC became unstable, with the following issues:
- The computer frequently froze and crashed during use.
- Boot times became increasingly slow, eventually leading to system failure.
- Files stored on the hard drive were no longer accessible.
- Attempts to run disk repair tools failed or caused further crashes.
Since a failing HDD can worsen over time, leading to complete data loss, an immediate professional data recovery solution was required.
Diagnosis & Evaluation
When the Lenovo desktop hard drive arrived at our secure cleanroom facility, we conducted a full hardware and file system diagnostic. Our findings:
- Bad sectors on the HDD – Causing freezing and slow performance.
- Read/write head degradation – Making file access unreliable.
- File system corruption (NTFS issues) – Preventing access to stored data.
Since continuing to use a failing hard drive can permanently corrupt files, we prioritized non-intrusive data extraction techniques.
The Recovery Process
1. Cloning & Imaging the Hard Drive to Prevent Further Data Loss
To preserve all recoverable data, we:
- Created a sector-by-sector forensic clone of the Lenovo desktop hard drive.
- Used specialized deep scanning tools to extract readable sectors while bypassing bad areas.
2. Repairing the File System & Extracting Data
Since the file system was corrupted, we:
- Rebuilt the Master File Table (MFT) to restore missing file directories.
- Repaired NTFS structures to make files accessible again.
3. Extracting & Verifying Client Files
Once the file system was restored, we:
- Recovered all lost documents, images, and archived data.
- Restored folder structures exactly as they were before failure.
- Transferred the fully restored data to a secure external backup device.
The Results: 98% Data Recovery Success
Thanks to our bad sector recovery and file system reconstruction techniques, we successfully recovered 98% of the client’s lost files, including:
✅ Work documents, spreadsheets, and PDFs
✅ Photos, videos, and personal data
✅ Organized file structures restored for easy access
The client was able to retrieve all essential files, preventing personal and professional data loss.
